摘要:

在过去的二十年里,系外行星直接成像领域的仪器技术有了很大的进步。美国航天局委托进行的四项大型概念研究中有两项涉及一种高对比度仪器,用于从空间对外地球进行成像和光谱表征:LUVOIR和HabEx。本白皮书介绍了美国和法国目前正在运行的8个光学测试平台的状况,这些测试平台旨在通过实验验证从太空对地球外进行成像的必要技术。他们探索了两个互补的研究方向:(i)日冕仪设计和制造;(ii)主动波前校正方法和技术。目前正在并行分析几种仪器架构,以便为设计未来的冠状动脉造影仪器提供更多的自由度。已经在实验室中证明了清晰离轴望远镜(HabEx类)的必要性能水平,目前正在作出重大努力,以便在今后两年中在分段和/或同轴望远镜(LUVOIR类)上重现这一成就。

英文摘要:

Instrumentation techniques in the field of direct imaging of exoplanets have greatly advanced over the last two decades. Two of the four NASA-commissioned large concept studies involve a high-contrast instrument for the imaging and spectral characterization of exo-Earths from space: LUVOIR and HabEx. This whitepaper describes the status of 8 optical testbeds in the US and France currently in operation to experimentally validate the necessary technologies to image exo-Earths from space. They explore two complementary axes of research: (i) coronagraph designs and manufacturing and (ii) active wavefront correction methods and technologies. Several instrument architectures are currently being analyzed in parallel to provide more degrees of freedom for designing the future coronagraphic instruments. The necessary level of performance has already been demonstrated in-laboratory for clear off-axis telescopes (HabEx-like) and important efforts are currently in development to reproduce this accomplishment on segmented and/or on-axis telescopes (LUVOIR-like) over the next two years.
